SPECIFICATION forming part of Letters Patent No. 777,693, datedlDecenibei 20, 1904i. Application filed May 6, 1904. Serial Nox 206,610.

To all 11171/0771/ it nur/y concern.'

Be it known that I, EDWARD D. PRIEST, a citizen of the United States,residing at Scheneetady, county of Schenectady, State of New York, haveinvented certain new and useful Improvements in Electric Locomotives, ofwhich the following' is a specification.

The present invention relates to improvements in electric locomotives,with especial To reference to the details of construction andarrangement of the cab.

The main object of my invention is to so organize the cab structure andarrange the controlling apparatus therein that the operator of I5 thelocomotive is centrally located while operating' the train, has a clearView of the track ahead, and has ready access to all the controlling'apparatus andother devices carried by the locomotive without leaving thecab. ln

zo this connection it is desirable that the cab be so arranged that whentwo or more locomotives are coupled together the operator or operatorsmay pass freely from one locomotivecab to another through coveredpassag'e-ways.

z 5 A further object is to arrange the sandboXes of the sanding' systemso as to utilize some of the waste heat generated by current fiowingthrough the rheostats or resistance grids to heat and keep dry the sandin said 3o boxes.

The invention therefore consists of an electric locomotive-cab whichcomprises a central compartment or cab proper in combination withcovered end passageways leading' to said 3 5 central compartment andsmaller compartments on each side of said end passage-ways forcontaining certain parts of the controlling apparatus, such asrheostats, contactors, &c.

The invention further consists of the combination,in anelectrically-propelled vehicle,o3t` a control system for the motorsthereof which includes resistance-sections, a compartment in which saidresistance-sections are located, and a sand-box in said compartment soarranged as to be subjected to the heat from said resistance-sections.

In the accompanying' drawings, which illustrate the preferred embodimentof my invention, Figure l is a side elevation of the locomotive. Fig. 2is a top plan view. Eig. 3 is 50 a longitudinal sectional elevation onthe line 3 3, Fig. 2. Fig. i is a sectional plan view on the line L 4,Eig. 1. Figs. 5 and 6 are seetional elevations on lines 5 5 and 6 6,respectively, Fig'. 2; and Eig'. 7 is an end view. 55

Referring now to the drawings, the truckframe is represented by 8, thecentral compartment of the cab by 9, the covered end pas sage-waysleading' to the central conn'iartment by 10 and 10, respectively, andthe com part- 6o ments on each side of said passage-ways by 11, 11",11C, and 11d. The end IjJassag'e-ways are so arranged that when two ormore locomotives are coupled together the operators may have anunobstructed covered passage-way from one locomotive-cab to another.

The central coimjiartmcnt or cab proper contains the master-controllers12 and the airbrake motornians valves 13 in duplicate, located indiagonally opposite corners. Fold- 7o ing seats 14 are provided for themotorman or operator. The said conliiartment also contains amotor-driven air-compressor 15 for supplying' compressed air to thebraking' and sanding' systems. An electric water heater 75 or boiler 16is also located in this compartment. This heater is to be employed invfurnishing steam for the heating' system of the several coachesconstituting' the train. The brakes may be applied by hand-power, if de-8O sired, through the agency of the handwheel 17.

The iioor 18 of the central compartment is considerably above the floor19 of the end passage-ways and is reached from said floor 19 by means ofthe steps 20. The space directly he- 8 5 neath the floor 18 is utilizedfor containing' airstorage tanks 21, cahle-boxes, tc. Said compartmentis provided with side doors or entrances 22, side windows 23, and endwindows 24. The operator, standing' upon the raised 90 iioor 18 near thecontroller .12 and looking out through the adjacent end window 2a, isable to see complctelyover the roofs of the covered end passage-way andits side compartments, and is thereby permitted a clear View of thetrack ahead.

The compartments 11, 11, .11, and 11d on each side of the endpassage-ways each contain a plurality of resistance grids or sections25, mounted on narrow cross-pieces 26, which are raised slightly fromthe floor 19. An open space is left between the cross-pieces 9.6 toallow a free circulation of air from below the cab through the chambercontaining the resistance-sections through the ventilating-flue 27 andout through the opening 28. This latter opening is preferably coveredwith gauze. Located partially in these flues and partially in thechambers containing the rheostats are sand-boxes 29, which are soconstructed as to utilize the side walls and partitions of thesecompartments as part of themselves and arranged to be subjected to theheat generated by the current passing through the resistances. The sandin the boxes is thus kept dry without eXtra heating apparatus. Access tothese sand-boxes is had through openings in the roofs of the sidecompartments. These openings are normally closed by the covers 30.Removable covers 31 are also provided for the front of each of thechambers containing the resistance-grids. The right-hand end of Fig. 3shows one of these covers in place, and the left-hand end shows thefront of the chamber with the cover 3l removed.

L The motors are controlled by the so-called separately-actuated Contactor contactor system of control. The power-actuated switches orcontactors of this system control the motor and resistance connectionsand are under the control of the master-controller l2. These contactors32 are located in the side compartments Il, 1lb, llc, and 11d, being'suspended from the inverted channel-bar 33 and separated from therheostat-chamber by the partition 34. The contactors are therefore quitereadily accessible for inspection and repairs. Furthermore, poweractuated reversingswitches 35, also under the control of themaster-controller l2, are located in these side compartments.

I aim in the appended claims to cover all modifications of my inventionwhich do not involve a departure from its spirit and scope.

That I claim as new, and desire to secure by Letters Patent of theUnited States, is-

l. In an electric locomotive, a cab comprising a central compartment,covered end passage-ways leading to said central compartment, andsmaller compartments in each side of said end passage-ways forcontaining parts of the controlling apparatus.

2. In an electric locomotive, a cab comprising a central compartment,covered end passage-ways leading to said central compartment, andsmaller compartments on each side of said end passage-ways forcontaining parts of the controlling apparatus, said central compartmenthaving its floor above the floor of said end passage-ways and beingprovided with end windows through which the operator may have a clearview of the track ahead over the roof of the end passage-way.

3. In an electrically-propelled vehicle, the combination of a controlsystem for the motors of the vehicle which includes resistancesections,a compartment in which said resistance-sections are located, and asand-box in said compartment so arranged as to be subj ected to the heatfrom said resistance-sections.

4. In an electrically-propelled vehicle, a motor, a controller therefor,resistances adapted to be connected in circuit with said motor, aninclosure for said resistances provided with a Ventilating-fine, and asand-box located in said flue in such a manner as to be subjected to theheat generated by the current vliowing through said resistances.

In an electric locomotive, a cab structure formed with a chamber inwhich rheostats or resistance-sections are adapted to be located, saidchamber being formed with a Ventilatingiue, and a sand-box located insaid iue.

In witness whereof I have hereunto set my hand this 4th day of May,1904.

EDWARD D. PRIEST.
